They're both level four, meaning they're likely to reoffend, according to police.

Van Buren police said they were notified on Tuesday that a level four sex offender came in to register. It's the second notice the county has received of a high-level sex offender moving into the area.

Two level four sex offenders are registered in Crawford County, but they are in prison. Now, two more are coming into the city.

Police said the latest, Adam Fernandez, just moved to a neighborhood on the south side of Van Buren. They said he was convicted twice in Oklahoma for sex crimes in the 1990s.

Fort Smith police said U.S. marshals arrested Fernandez after he failed to register in the Fort Smith area after crossing state lines.

"Class one and two, you know they're low, but when it gets up there, three and four, you don't know when they're going to take them (the children), we watch," said Brenda Brown, of Van Buren. "We come out and watch our children get on the bus, because they get on the bus at 6:45 a.m. It's rough, it's really rough."

People who live in the Van Buren neighborhood where Fernandez now lives are worried for their children.

"It's kind of hard, you know, to explain to (the children)," Brown said.

The second offender, Shannon Boydston, is living near Cedarville and paroled just last week after serving just three years of a 20-year sentence.

The sheriff said he'll do his best to hold high-rated sex offenders like Boydston accountable.

"As far as I'm concerned, he's a free man. He's done the crime. He's done the time. You know, we're just going to make sure he does what he's supposed to do continuously," said Crawford County Sheriff Ron Brown.

Van Buren police said they are in the process of printing fliers and giving them to people who live within a 2,000-foot radius of Fernandez's new home on Flat Rock Circle.
